In the previous article GridView Select Multiple Rows you learnt the multiple row selection in GridView control. Here you will get the C# code sample to select all the gridview rows using single checkbox server control. You can highlight the selected rows with different color and Font state Bold. If you want to use the selection values on different ASP.Net

To enable the GridView Paging and Sorting to update the GridView Data without refreshing the ASP.Net web page AJAX Extension controls are used. UpdatePanel is used to hold the GridView control that triggers the events for the controls placed inside it. By Default UpdatePanel triggers the asynchronous postbacks for its child controls.

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels .Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

Did you tried before to drag a RadioButton control inside a Gridivew templatefield, and then you attempt to select these RadioButtons , you will notice that the behavior of RadioButton control will be changed and it will work just like the behavior of checkbox control! the user will be able to select more than one radiobutton in the grid!

Before explaining the article, I would like to thank all readers who read my article and voted for it. Your appreciation for my article gives me strength to write more good articles. Hope in future I will get your valuable comments and suggestions. Now I won't waste your time and come back to the topic. I have written this article on 'Ajax Enabled Gridview Using JavaScript in ASP.NET'. In this article, I will show you how to make a Gridview using a simple HTML table, JavaScript and XML HTTP for Ajax call without using any ASP.NET control.

This article shows 2 common tasks with the ASP.NET GridView: Binding a List (generic) of objects as DataSource and on clicking a row, getting the values of the selected row by a javascript function. In the example a List with User-objects is displayed. On clicking a row containing the data of a User-object, the Id of the object is used to get the address of the user by an Ajax-call and display it in a details-field.

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

I'm starting a small website that will be backed by a database, and will allow a small number of users to authenticate and select an entry in the database, and then view (and optionally update) a corresponding entry (think master-detail).

I have some flexibility in how I'll do this, but I'd really like to incorperate some newer AJAX style coding, eliminating some page postbacks. I think this is a great opportunity to learn the concepts well.

I'll probably go with an ASP.NET 4.0 site. From what I've seen there are MANY ways to go about this:

-WCF Data Services to expose the data, and consume in ASP.NET

-Page methods to expose the data, separate method to update the data

-I'd rather avoid the UpdatePanel because I'm really looking for a full hands-on approach, with learning client side scripting being an objective as well.

Beyond that, it seems that one can use jQuery to build clientside templates, but also one can use the ASP.NET AJAX template engine (in ASP.NET 4.0 I believe).

A concern I have: users should only be able to work with the data exposed via these endpoints if they are logged into the website. Hopefully I can somehow reuse the ASP.NET forms authentication cookie for this purpose.

When outside any panel or table it is working well, but as soon as I put it in a <asp:panel> or table I get a strange error which seems to be on client-side but I don't understand what's happen here. Here is the code and code-behind and Javascript.

Hi.I have defined a field validator that works fine on normal behavior on a page:<asp:RequiredFieldValidator runat="server" ErrorMessage="errroooorr" ControlToValidate="TextBoxHouseNumber" Display="Dynamic"></asp:RequiredFieldValidator>Now if I dont insert any text in the TextBoxHouseNumber field, and push submit, the FieldValidator fires as it should. But if I now click a button that automatically fills the TextBoxHouseNumber with text from a Jquery/Ajax function, the field validator still shows. ItÃÂ´s like "Hey, the user hasnt made any changes to the textbox, so I wont bother check it".How can I overcome this problem?Thanks alot! :)

Hi Dude,
I have a big problem in Jquery ajax call. I am calling the web service whenever click the update button. I have a separate web service class, in which consist of few methods. When I calling the web service method, I have made the error handling and log the error information in db after that I have to override the "ex" that means error object to XMLHttpRequest. Is it possible to assign the sqlexception to ajax object (xhr) in vb.net? Please help me its much more useful for me.
Thank in advance.

Dears,
I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.
How can I do this?
